Khagantak-243 Long-Range Glide Bomb
Why in News?
The Indian Air Force conducted a successful drop trial of the Khagantak-243 glide bomb on 2 September 2026. A Sukhoi Su-30MKI fighter aircraft launched the precision weapon during the trials.
Defense agencies designed the Khagantak-243 glide bomb as a high-precision munition for long-range stand-off attacks. This successful test significantly advances India’s self-reliance goals in airborne precision weaponry.
What is a Glide Bomb?
A glide bomb is an air-launched weapon without continuous engine propulsion. The munition deploys aerodynamic wings and fin surfaces after release.
These wing surfaces generate lift and glide long distances toward distant coordinates. Stand-off delivery protects the launch aircraft by keeping pilots outside hostile air defence bubbles.
| Weapon Category | Operational Advantage | Primary Purpose |
| Traditional Gravity Bomb | Inexpensive and simple to produce | Direct overflight delivery on exposed ground targets |
| Powered Cruise Missile | Very long operational range | Low-altitude terrain-hugging strikes against high-value assets |
| Precision Glide Bomb | Stand-off range at lower cost | Accurate strikes against defended positions from safe distances |
Technical Design and Flight Capabilities of Khagantak-243
The Khagantak-243 integrates high aerodynamic efficiency with a reliable explosive payload.
| Technical Parameter | Specification Detail |
| Maximum Stand-Off Range | More than 140 kilometres |
| Release Altitude | Approximately 12,000 metres (39,000 feet) |
| Airframe Structure | Cylindrical body with mid-body swivel glide wings |
| Control Actuation | Five aft aerodynamic control surfaces |
| Warhead Configuration | Mk-81 general-purpose blast-fragmentation warhead |
| Mid-Course Guidance | Inertial Navigation System (INS) + Jam-resistant Multi-GNSS |
| Terminal Guidance Options | Electro-Optical/Infrared (EO/IR) or Passive Homing Head (PHH) |
1. Aerodynamic Configuration
- The bomb features a sleek cylindrical body to minimize aerodynamic drag.
- Mid-body swivel-type wings deploy automatically after aircraft separation.
- Five aft control fins adjust the flight path and execute precise glide maneuvers.
2. Dual-Layer Guidance Architecture
- Inertial Navigation System (INS): The INS calculates position independently without external radio signals.
- Multi-GNSS Satellite Receiver: Jamming-resistant satellite reception refines mid-course trajectory accuracy.
- Terminal Seekers: The weapon supports Electro-Optical/Infrared (EO/IR) or Passive Homing Head (PHH) sensors. These seekers locate and strike defended targets with exceptional pinpoint precision.
Development Partners and Industrial Collaboration
The weapon represents an effective public-private partnership model in Indian defense production.
| Partner Entity | Institutional Role | Primary Contribution |
| JSR Dynamics | Private Aerospace Designer | Engineered the aerodynamic airframe, swivel wings, and flight control systems. |
| Bharat Electronics Limited (BEL) | Navratna Defense PSU | Supplied the guidance avionics, flight electronics, and sensor subsystems. |
| Indian Air Force (IAF) | End User & Testing Agency | Conducted integration checks and executed the live drop trial. |
Launch Platform: Sukhoi Su-30MKI Multirole Fighter
The Indian Air Force selected the Sukhoi Su-30MKI as the primary integration platform for the trials.
- The Su-30MKI is a twin-engine, twin-seat multirole combat fighter.
- Hindustan Aeronautics Limited (HAL) manufactures the aircraft under license from Russia.
- The jet carries heavy payloads and delivers air-to-ground precision weapons from extreme stand-off ranges.
Strengthening Self-Reliance: Atmanirbhar Bharat in Defense
This test aligns with national defense modernization policies. The Government of India launched the Make in India program in 2014 to boost domestic manufacturing.
The Atmanirbhar Bharat initiative further drives self-reliance in strategic technologies. Developing precision-guided glide bombs domestically reduces import dependence and ensures robust tactical supply security.
